An updated version of the NEX-7, the NEX-7n , may be available in April.

Possible changes:

"The specs of course cannot be confirmed at the moment, but according to the tip, the NEX-7n will feature a 24MP camera with phase detection pixels on its sensor. This will be a new sensor and will not be the same one on the NEX-7. Apparently the internal circuitry has also been redesign and supposedly solves the overheating problem."

I would also think / hope that Sony would add a fully articulated touch screen LCD with a properly sorted out WiFi system, and totally revamped menu system to this top of the line camera.

I'd also like to see Sony introduce a really first class "everyday" zoom lens with this new camera. Something like a 16-105 mm collapsible PZ type of lens built to G series spec.'s.
